• To select all masks on a layer, select a mask on the layer, and choose Edit > Select All or press Ctrl+A (Windows)
or Command+A (Mac OS).
• To deselect all masks, press Ctrl+Shift+A (Windows) or Command+Shift+A (Mac OS).
• To select an adjacent mask on a layer, press Alt+accent grave (`) (Windows) or Option+accent grave (`) (Mac OS)
to select the next mask, or Shift+Alt+accent grave (`) (Windows) or Shift+Option+accent grave (`) (Mac OS) to
select the previous mask.
• To deselect a mask, click anywhere other than on the mask.
• To remove a vertex or segment from a selection, Shift-click the vertex or segment.
To use the Selection tool when the Pen tool is selected, hold down Ctrl (Windows) or Command (Mac OS).
Select masks in the Timeline panel
1 Click the right arrow next to a layer name to expand it.
Click the right arrow next to the Masks heading to expand it, revealing all masks on that layer.

3 Do any of the following:
• To select one mask, click its name.
• To select a contiguous range of masks, Shift-click the names of the first and last masks in the range.
• To select discontiguous masks together, Ctrl-click (Windows) or Command-click (Mac OS) the names of any
masks you want to include.
Note: You can select only whole masks in the Timeline panel. To select individual vertices on a mask, use the Composition
or Layer panel.
Lock or unlock masks
Locking a mask prevents you from selecting it in the Timeline, Composition, and Layer panels or setting it as a target
in the Layer panel. Use this feature to avoid unwanted changes to the mask.
In the Timeline panel, expand the Masks property group.

2 In the A/V Features column, click the box underneath the Lock icon
unlock. A mask is locked and cannot be selected when its Lock switch is selected—that is, when the Lock icon
appears in the box.
Note: To unlock multiple masks at one time, select one or more layers and choose Layer > Mask > Unlock All Masks.
To isolate selected masks and hide others, choose Layer > Mask > Lock Other Masks, and then choose Layer > Mask
Hide Locked Masks.
Move vertices in free-transform mode
You can scale and rotate an entire mask or shape path (or selected vertices in one or more paths) using the Free
Transform Points command. When you use this command, a free-transform bounding box surrounds the selected
vertices, and an anchor point appears in the center of the bounding box to mark the anchor point for the current
transformation. You can scale and rotate the selected vertices by dragging the bounding box or its handles. You can
also change the reference point from which the vertices are rotated or scaled by moving the bounding box anchor
point. The free-transform bounding box handles and anchor point exist independently of the handles and anchor
point for the layer.
